La Profilée - Structural Necessity and Ontological Status: On the Boundary Between Forced Structure and Reality Claims

La Profilée (LP) establishes the persistence condition IR = R/(F·M·K) ≤ 1 as the unique structure governing persistence under real transformation (Paper 103). Paper 117 further shows that this structure follows from the minimal conditions required for persistence to be a meaningful concept. Paper 118 establishes that this condition is recurrently instantiated across multiple independent domains. This paper clarifies the epistemic status of these results. It distinguishes structural necessity from ontological claim and establishes a precise boundary: structural derivations determine what must hold for coherent description, while empirical observations determine where such structures are instantiated. Neither step alone nor in combination establishes that reality is identical with the derived structure. The result is a clarification, not a weakening: LP is established as a structurally forced and empirically recurrent constraint on persistence, while the ontological status of that structure remains outside the scope of rational derivation.
